After attaining me no cycle of birth and death.

idam jnanam upasritya,mama,sadharmyam agatah,

sarge pi no pajayante,paralaye na vyathanti ca.--2

By attaining the disincentive knowledge and complete realization of me exempts the being of rebirth since he has no fear of repeated birth at the time of creation and dissolution of the universe.
After knowing the juana[knowledge]sages not ordinary human becomes self realized and they never born in the time of creation and never disturbed at the time of dissolution.according to Hindu scriptures there are two times,one is beginning of creatures it is called as'utpati'and second is dissolution it is called as 'paralha'.in the time of 'parlaha' every thing finishes.creatures reborn at the time of creation.'utpathi'.in the time of dissolution every creature loses its physical form but not its subtle form.it remains as a blue print of the body.at the time of creation it reborn.as seeds of grass reborn on next season.But self realized souls are one with the universe self[God].It is like a stream which dissolves with the ocean.

Chapter-14th.The highest knowledge.

param ghuyah pravaksyami,jnananm,jnanam uttamam,

yaj jantva munayah sarve,param siddhim ito gotoh.---1

The Lord Krishana said,"I shall again ravel to you that knowledge regarding the supreme soul by knowing which the wise saints attained freedom from cycle of birth and death.
This chapter of Gita is the highest knowledge which can liberate any human being.so this is supreme.The very roots of buddha's vippasana comes from this chapter. because gita is a work of the ancient knowledge.Dr Radhakrishana [former prime minister of India]wrote and he compared solakas of gita and vadas.his view is that this is work for a human to find his real nature[self]which has described in vads.

who knows different knower and known he is wise.

Ksetraksetrajnayor evam,antaram jnanacksusa,

bhutaprakrtimpksam ca,ye vidur yanti te param.--33

Those wise minds who understand fully the doer and the deeds.and difference between Field and knower of the field along with their harmonious unity attains salvation.
It is clear in this chapter that who knows difference between nature and self or field and knower of the field he is wise,enlightened,self realized.these words are different but meaning is the same.he has attains his goal.the main problem is this we identify ourselves with body and mind.we do not know that we pure self[sat chit ananda]we come to know this difference in deep meditation.This is a real map of 13chapter in our hand and we can go on journey of the self.my guru st nikka singh ji used to say this chapter is very important.if you can follow this chapter you will easily find your goal of self-realization.

This is the 13th chapter entitled the yoga of the distinction between the field and the knower of the field.

sun gives light to universe like self to body.

yatha,parkasayaty ekha,krsnam lokam imam ravih,
ksetram ksetri thatha krtsnam,parkasayati,bharat.--32

As all the light that illuminates the universe comes out of Sun,in the same manner all so souls are sourced from the super- soul.
As only one sun is giving light and heat to the universe,likewise our self which we can not see due to subtle gives energy to body,mind, intellect to do functions.by the force of self our body is doing its actions.

Beyond beginning and end.

yatha sarvagatam sauksmyad,akasam,no 'palipyate,
sarvatrd vasthito dehe,tatha tma no palipyate.--31

Being unattached to any deed done by the body and maintaining that imperishable non participatory stanch the soul maintains the Independence from all deeds and thoughts,thus remaining like the open sky.
As ether is everywhere,there is not any thing like earth,star,planet,which does not exist in the sky.we heard about five elements of nature as,earth,water,air,fire and sky.
Sky is subtler than other elements,from solid to subtle are like this earth,water,fire,air and sky.every thing takes shape[form]in the sky and ends in sky[space].because it is subtler than other elements.they depends on it.likewise our soul is subtler than other elements,and it does not depend on other elements.it has not form,color,etc.

Self is within all things

anaditvan nirgunatvati,parmatama,yam avyayah
sarirastho pi kaunteya,na karoti na lipyate.--30
Being beyond beginning and end this self[super being],the one with resides within yet keeps oneself untainted by the karmas and remains neutral
Oh![Arjuna]son of kunti.one point strikes in my mind,no doubt in those days when gita was written people regards the mother too much. Because Arjuna was son of king Pandwa.but still here is the name of mother of Arjuna,kunti.so we can see the regard of a lady.
The meaning of this solaka is oh!Arjuna son of kunti this self is imperishable.without beginning and without end.which thing begins it will come to an and one day.But self is beginning less.so it has no end.like sky.it has not beginning and end.
It has no qualities as long,short,red or blue.our mind imagine the objects.but our self is beyond from these qualities.our self dwells in our body.It supports our mind,sense organs,intellect like electricity,it is necessary for our body to move but still it is unmovable.

everything is centred in one.

yada bhutaprthagbhavam,ekastham anupasyati,
tata eva ca vistaram,brahma sampadyate tada.--29

When he sees that the manifold state of beings is centered in the one and from just that it spreads out,then he attains Brahaman.
When one sees that everything our deeds,our feelings,emotions,are centered in self.we are as extension of the super soul.he becomes the witness these actions of body,mind.beacuse they are sent by nature according our karmas[deeds]. Because of this conviction one becomes merely a watcher not participate to all the actions of nature.rather one treats oneself a cosmic manifestation of the super soul.
There is a story of unglimal in Buddha scriptures.he was a robber.he swore to kill 1000 people.he met Buddha in a forest.so he became his follower and get enlightened.Buddha sent him in a village to get alms.when people of the village saw him they threw stones on him.but he became silent and did not respond.they killed him.he remained in witnessing.when other Bhksus ask Buddha where he has gon.Buddha said,"my son go no anywhere.he gets enlightened."
